Hello,
I don't think is weird :
1- RIP (assume you have rip version 1)see the majors networks 65 66 67 without
the mask, so it assume a mask of /8 normal: the link in the /24 is for the SAME
major network. As for IGRP.
2- If you want to do some think like as, in a lab you could define secondary
address on R2 for the 3 major network.Different form those you use allready.
maybye there is another solution with loopback
<here i m not to sure, it is late>
Ex:
r2
int ...
ip add 65.1.1.x 255.255.255.0
ip add 66.1.2.x 255.255.255.0 secondary
ip add 67.1.2.x 255.255.255.0 secondary
ip add 68.1.2.x 255.255.255.0 secondary
hope it help you a little
Best regards
